Benefits of technology
The present invention provides a mold-tool system and a mold-runner system for use in a molding process. The mold-tool system includes a frame assembly and a set of shooting-pot assemblies, while the mold-runner system includes a hot-runner frame assembly, a set of shooting-pot assemblies, a melt-distribution assembly, and a sensor assembly. Each shooting-pot assembly has independent control, allowing for individualized control and adjustment during the molding process. The computer system includes a processor, a sensor-interface module, a control-interface module, and a controller-usable medium, which monitors and controls the shooting-pot assemblies in response to the sensed signals. The technical effects of the invention include improved control and efficiency during the molding process, resulting in improved quality and productivity.
Problems solved by technology
It was, however, expensive to produce, prone to cracking, and highly flammable.
If the plastic material is very stiff, it will require more injection pressure to fill the mold, thus more clamp tonnage to hold the mold closed.

Abstract
A mold-tool system (105) for use with a molding-system platen structure (107), the mold-tool system (105) camprising: a frame assembly (103) being connectable with the molding-system platen structure (107); and a set of shooting-pot assemblies semblies (204) being supported by the frame assembly (103), wherein control of each shooting-pot assembly of the set of shooting-pot assemblies (204) is independent.
Description
TECHNICAL FIELD[0001]An aspect of the present invention generally relates to (but is not limited to) a mold-runner system having a set of shooting-pot assemblies wherein control of each shooting-pot assembly of the set of shooting-pot assemblies is independent.BACKGROUND[0002]The first man-made plastic was invented in Britain in 1851 by Alexander PARKES. He publicly demonstrated it at the 1862 International Exhibition in London, calling the material Parkesine. Derived from cellulose, Parkesine could be heated, molded, and retain its shape when cooled. It was, however, expensive to produce, prone to cracking, and highly flammable. In 1868, American inventor John Wesley HYATT developed a plastic material he named Celluloid, improving on PARKES’ invention so that it could be processed into finished form. HYATT patented the first injection molding machine in 1872. It worked like a large hypodermic needle, using a plunger to inject plastic through a heated cylinder into a mold. The indus...
